Claims. (01. 156-38) This invention relates to window screens and tom member 15 of the section iii are provided particularly to that type commonly called exwith longitudinally-extending, centrally-positension screens, which are adapted for insertion tioned slots 83. These slots 18 are undercut for in window frames of various widths. the purpose of retaining anti-friction devices 19,

It will be readily seen that respectively. The top member l4 and the botany movement of the member 35 in the direction 55 of the arrow will bring the detent 30 out of engagement with the perforated bar 23.

From the foregoing description of the device, and its method of operation, it will be obvious that, when the screen sections 19 and II are relatively moved or adjusted, the anti-friction members l9, located in the grooves or slots, will eliminate any binding or sticking action, and with the locking detent 39 working and engaging with the perforated bar 23, will lock the two sections against retraction from the outside and also from the inside, unless the locking dog is released, and will permit extension of the section. It will also be apparent that the provision of the bars 28, 2! and 23 will not only lend rigidity to the entire screen assembly, but will greatly facilitate the operation of inserting the screen sections within the window easements.

Modifications of the structure herein described may be suggested to those skilled in the art to which the invention pertains, but it is to be understood that my invention includes all embodiments falling fairly within the scope of the appended claims.

I claim:

1. A window screen installation including two relatively slidable screen sections, a centrally disposed bar secured directly to the screen meshes of one section, and a locking detent secured to the second section and engageable with said centrally disposed bar.

2. A window screen assembly including two relatively slidable screen sections, a bar extending transversely of one section, and provided with means for securing it to the screen mesh, a

rigid rod carried by the top and bottom of each section, a metallic clip secured to the other section, and provided with a housing embracing said bar, and a locking detent carried by said clip and engageable with said transversely extending bar.

3. A window screen installation including two relatively slidable screen sections, a bar extending transversely of one section and secured to the screen meshes by spur clips formed thereon and adapted to be extended through the interstices in the mesh and be pressed around a second bar positioned on the opposite side of the screen mesh, whereby to retain said first named bar in operative position, a metal clip secured to the second screen section, and a manually-operable locking detent carried by said clip and engageable with said transversely extended bar.

4. A window screen installation including two relatively slidable screen sections, a centrally disposed bar secured directly to the screen meshes of one section, a metallic clip secured to the other section, a locking detent carried by said metallic clip and engageable with said centrally disposed bar, and a manually-operable releasing member slidably fastened to the locking detent.

5. A window screen installation including two relatively slidable screen sections, a centrally disposed perforated bar secured to the screen meshes or" one section, a metallic clip secured to the other screen section and having slidable engagement with the perforated bar, and a manually-operable locking detent carried by said metallic clip, and adapted for engagement with said perforations of the centrally disposed perforated bar.
